ACCOUNTING MACHINE.

Application ed November 21, 1918. Serial No. 263,625.

To 177 who/m. 'it may concern.'

Be it known that I, Anios II. Hna/Lm', citizen of the Ifnited States ofAmerica, residing at "Toi-wood, in the county of I-Iamilton and State ofOhio, have invented certain new and useful Improvements in AccountingMachines, of which the following is a specification.

The present invention has to do particularly with accounting machinesfor adding and listing purposes and involves primarily certainimprovements in machines of the type disclosed .in U. S. patents ofWhite No. 1,192,721 issued July 25, 1916, and Runquist No. 1,213,268issued January 23, 1917.

Among the objects of the invention have been the reorganization ofcertain portions of the mechanism of the machine whereby I have obtaineda positive actuating means for effecting release of the amount keys andthe associated indexing parts, which are usually locked upon depressionof said keys; the employment of peculiar interlocking instrumentalitiesbetween the total and the subtotal keys acting to avoid improper actionof these keys; provisions whereby the device controlling repeatoperations of the machine are improved; and special provisions wherebythe totaling keys are adapted to effect release operation ofthe repeatkey should the latter be in its depressed position or actuatedposition,. when either the total or sub-total key is operated.

The present invention resides in other specific features of mechanismwhich will be more fully disclosed hereinafter, and this applicationconstitutes a division of my pending application for patent foraccounting machine, Serial No. 17 3,7 90, liled June 9, 1917.

In the accompanying drawings, Figure 1 is a right vertical sectionalview through the machine embodying the improvements of this inventionand bringing out the general arrangement of the key board accumulatingand printing mechanisms. i Figure 2 is a vertical sectional view showingmore clearly the driving connection between the main actuator shaft andthe key releasing device.

The machine to which I have adapted my improvements embodies certainadding, listing, and other auxiliary registering mechanisms presented indetail in the co-pending application for patent of Mann and Hawley,Serial No. 48,544, filed September 1, 1915, now issued as Letters Patent1,298,751, April 1, 1919. In view of the disclosures in the previouslyidentified Letters Patent., it is not deemed necessary to recite indetail the-construction and operation of the adding machine thereinpresented. Generally speaking, the machine shown in the drawingsannexted hereto include a main actuator in the form of a shaft 625operated in the well-known manner, and the usual key board includingrows of amount keys 100 with associated special operation keys. There isemployed additionally known listing mechanism includng type. carrers anda known type of paper carriage.

The accumulator 311 is located at the front of the machine so thatregistrations thereof may be observed through suitable openings 311a inthe machine case. The keys 100 control the indexing mechanism for theaccumulating and printing instrumentalities, in a manner substantiallyas set forth in the aforesaid )Vhite patent. There may be provided, asshown in Figure 6, 4certain special operation keys including a repeatkey, designated 142, an error key designated 137, a sub-total key,designated 136, and atotal kev, designated 135.

As seen best in Figure 1 the accumulator embodies the usual addingwheels 1li/"2, the pinions of which are engageable by adding racks 301,the movement of the latter being effected by operating levers 500connected at their front ends with adding racks, one for each rack, andat their rear ends each connected with a type carrier 706. A spring 616is connected with an arm 500 projecting downwards from the centralportion of each lever 500 and normally tends to draw the front end ofthe lever downwards and raise its rear end. Such movement of the lever500 is restrained, however, by a restoring bar @il contacting' with theupper edge of the rear portions of the several levers and carried by apair of arms 505 having irregular slots formed therein.

rllhe racks 801 and type carriers 700 are adapted for differentialmovement under the control of the indexing mechanism,y directly actuatedby the keys 100. lt may be noted that on each actuation of the shaft625, the governor shaft G26, to which said lever 50S is secured, will bepartially rotated by means of a flexible connection comprising a springand forked rod as clearly' shown in Figure 2. Afiixed to the governorshaft 626 is a pair of downwardly extending arms 512 provided with studs655, which enter the crooked slots in the arms 505. rllhus the operativeconnection established by the parts just mentioned is adapted to raisethe restoring bar 641 by the aforesaid rollers cooperating with theirregular slots in the bars supporting the said restoring bar 641thereby permitting springs 616 to draw the actuating` racks 801downwardly to an extent to determine by the indexing mechanism when themachine is operated.

rlhe extent of movement of the levers 500 is controlled by the keyboardmechanism including the keys 100 and suitable indexing stops 110 (seeFigure 1), one of which is provided for eac-h key 100, those for eachrow of keys being superposed. Depression of a key 100 of a certa-in rowforces rear- Wardly by means of a` pin 100 the locking bar 120,disengages the front end of said bar from a projection 301 on thecorresponding rack 301 and simultaneously projects forward an indexingstop 110 into the path of said projection 301. According to whicheverstop 110 is rendered operative, so will be the extent of movement of theadding rack 301 and lever 500 controlled by said stop. In this way,differential movement yof each lever 500 is controlled so to cause oneor more increments of movement of the adding pinion of the associatedadding wheel and corresponding movement of the type carrier to positiona type of the latter' at the printing point.

Engagement of the customary wipe pawl with the three armed lever isdifferentially controlled by a main total lever, an auxiliary totallever, and a sub-total lever, which are adjusted for controlling saidengagement by manipulation of certain special operation keys includingthe total, and sub-total keys. llt is not believed necessary to presentwith detail the operation of the said levers in view of the identified)White patent.

It will be observed that the listing mechanism is of the known typepresented in the `White Letters Patent and comprising a series ofvertically moving type carriers 706 pivoted at their lower ends to thelevers 500 and carrying type spaced to correspond with the predetermineddegrees of movement of the levers 500. Printing impression is producedby impingement of the hammers 7 00 against such type as may bepositioned at the printing line.

It has heretofore been a practice to depend upon a spring actuated pawlcarrier as a means of releasing the manipulative keys upon the return ofthe main actuator to normal (see member 106 of Figure 15 of Vhite patentaforesaid). This construction in practice is not altogether satisfactoryin that sometimes the pawl carrier does not respond to the ordinaryspring tension, due perhaps to friction on its mounting or the gummingof the lubricant used, or other causes. Therefore, as shown in Figures 2and 7, I have provided, in the upper arm of the lever 508, a cam slot508 adapted to receive the lateral stud 141-0a farried by an arm 140(see Figure 9) of the lever 140 which is mounted on the keyboard sidepiate 128R (see Figure 8). The engagement of the stud M0a with the slot50S is such that as the lever 508 oscillates with the shaft 626 to whichit is fixed, the stud 140a will initially be actuated by the lever 508to shift the lever arm 140 upwards, and afterwards the stud. will becarried out of the slot and then remain in engagement with the arc 508',which forms a dwell. It is to be borne in mind that the initial movementof the main actuator causes movement of the lever 50S in the dir ctionindicated by the arrow (see Figure 7) thus itis plain that upon returnmovement the stud 140 will be reengaged with the upper wall of the slot508 of the lever 508 and the pawl carrying lever 140 (see Figure 9)positiveiy actuated through movement of the arm 140 downwards. Thislever 140 carries certain key release actuating means now to be pointedout and analogous to those now known. Y

Referring to Figures 7 and 9, mounted on the upper end of the lever 140is the trip pawl 141 provided with a tooth 141 which is adapted toengage the stud 75 associated with the key release shaft llt-261 seen inFigure 3. The pawl 141 has a stop projection 141 which engages the car140, formed on the upper end of the lever 140, and serves to hold thesaid pawl in operative position against the tension of. the spring 1411.rlhe function of the repeat key is to disable the pawl 141 and thecoacting shaft fir-261 as is well known according to the identifiedWhite patent; the means adopted for this purpose in the presentinstances consists of the lever 76 mounted pivotally on the side plate123R and, by means of the slot 7 6 and the stud 142, connected with therepeat key 142. At the front end of the said lever 76 is a surface 76over which the stud 141b rides when the repeat key is depressed as shownin Figure 7. The up or inoperative position of the key 142 is shown inFigure 3. Then in the latter position the key 14.2 permits the lever 76to remain lowered or tilted so that the tooth 141 of the pawl 141 mayengage the stud 75 of the key release shaft A-261, on the returnmovement of the shaft 626, thus rocking the shaft A4261 to release thekeys after the ordinary manner. The positioning of the parts as inFigure 7 on depression of the key 142 simply renders the part 141inoperative to perform the stated function.

The devices which lock the total and subtotal keys against mis-operationare best shown in Figures 7 and 9. It will be observed that supported bysuitable mountings on the keyboard side plate 123B, is a slide member166 with the two beveled projections 166 and 166 arranged for engagementby the studs 136 and 1.35 projecting laterally from the sub-total andtotal keys respectively; these members are so proportioned that upondepression of either of the two keys 135 or 136 the member 166 will bemoved away from the key depressed and into the path of the stud carriedby the key not so manipulated. However, if an effort is made to depressboth keys at the same time, their respective studs will engage againstthe bevel projections 166 and 166 of the member 166, locking the saidkeys against simultaneous effective manipulation.

Referring to Figures 3 and 7, it will be noted that the keys 135 and1.36 carry each a second laterally projecting stud 135 and 136,respectively. which normally stand above the path of the hookprojections 133 on the upper edge of the slide bar 1.33, but when eitherkey is depressed, the said second stud thereon is in a position such asto permit the corresponding hook projection 133 to pass above the saidstud.

The bar 133 is positively connected with the lever 140 as shown inFigures 3, 5, 7, and

9 wherein the stud 141C, on which the pawl 141 is carried, projects intoa slot 133 cut into the lower edge of the bar 133 establishing' apermanentV connection between saidk parts. The bar 133 is thereforepositively driven in its excursions which are made upon the lirst andlast degrees of movement of the main actuator; thus it will beunderstood how the keys 135 and 136 are locked against manipulation whenthe main actuator is positioned otherwise than at normal.

Adjacent to the slide .member 166 and mounted to slide on suitablesupports is the bar 77 provided with bevel projections 77 and 77 whichupon depression of the keys 135 or 136 are engaged to cause rearwardmovement of the bar 77, the end 77 of which is adapted to engage therepeat key 142 at its lower end. By this action the bar 77 will rock therepeat key 142 on the stud 142", to disengage the same at its notch 142Xfrom engagement with the keyboard t'op plate 124. This operation permitsrestoring action of the spring 142g to restore `the key 142 to normal,presuming the said repeat key 142 is in the depressed position (shown inFigure 7) when the total or subtotal key is manipulated.

Figures 3, 6, and 8 show the manner in which latches such as 134cooperate to hold the total and sub-total keys depressed; also thearrangement of the release bar 133 which cooperates with the latches 129by which the numeral keys 100 are retained in depressed positions in themanner fully set forth in the White patent. The latches 129 aresupported by suitable plates 128, the uppermost of which is shown inFigure 6.
